Abstract

An automatic transmission is provided with a frictional engagement member (1) that is operated by hydraulic pressure (Pc) for shifting the automatic transmission, and includes an air vent opening (5). An automatic transmission controller includes a pressure regulator (2,3) and a control section (4). The pressure regulator regulates the hydraulic pressure in response to a hydraulic pressure control signal. The control section performs an air vent operation of venting air from the frictional engagement member through the air vent opening (5). The air vent operation includes: a preliminary operation of setting the hydraulic pressure control signal to a preliminary pulse indicative of a preliminary value of pressure, wherein the preliminary value is lower than a normal value of pressure; and a normal operation of setting the hydraulic pressure control signal to a normal pulse indicative of the normal value, wherein the normal pulse follows the preliminary pulse.
